[0010]

EXAMPLES Examples of the present invention will be described below with reference to the prior art.
This will be described in detail with reference to FIGS. FIG. 1 , FIG.
Figure 12 shows an embodiment of a mounting structure of a weather strip of the present invention, as shown in FIG. 7, the weather strip when it is attached to the door frame portion F of the peripheral portion of the motor vehicle door D shown in FIG. 1 Mounting structure. Reference numeral 1 denotes a door panel inner, 21 denotes a weather strip, and a fitting recess 6 deeply recessed along the mounting surface 5 between the sealing portion 3 and the mounting base portion 4 which are in close contact with the opening peripheral portion 2 of the vehicle body when the door is closed. Is formed. Further , an adhesive tape 7 or a flexible magnet plate 7 is attached to the mounting surface 5 in order to facilitate temporary fixing at the time of assembly.

The garnish 8 is attached by fitting its extended end 8a deeply into the fitting recess 6.
The mounting base 4 and the door panel inner 1 are hidden, and the mounting base 4 is strongly clamped between the door panel inner 1 and the extension end 8a. The work of assembling the weather strip made of a sponge rubber body to the door is performed by attaching an adhesive tape 7 or the like to facilitate temporary fixing, and furthermore , the material of the fitting recess 6 is made of high hardness JIS HS50 °.
If you conduct composite molded solid rubber to 95 ° assembling can be made easier.

When the projection 1a is formed on the door panel inner 1 as shown in FIG. 7 , the mounting base 4 is more reliably held by the extended end 8a of the garnish 8. That is, when the door is opened and closed in the opening and closing direction A shown by the arrow, the weather strip 21 is always compressed toward the projection 1a with respect to the opening edge 2, and the falling off is more reliably prevented. Incidentally, when providing a projection 1a to the door panel inner 1, as shown in FIG. 7, the mold of the upper and lower during manufacture M,
If the panel P is pressed by providing the concave and convex portions Ma and Mb on M, it can be manufactured at low cost.

[0013] mounting structure of the weather strip shown in FIGS. 8 to 10, of the door body Da portion shown in FIG. 1 B-
The cross section of section B shows different embodiments. That is, the weather strip 21 shown in FIG. 8 is such that the end 9a of the extended door trim 9 is deeply fitted into the fitting recess 6 which is deeply recessed in the mounting base 4, and the extended end 9a
Thus, the mounting base 4 is sandwiched between the inner panel 1 and the door panel inner 1.

The weather strip 22 shown in FIG. 9 has a mounting base 4 having a U-shaped cross section with the core 10 buried therein, and a projection 11 formed on the inner wall of the recess to form a fitting recess 6a. I have. An extended end 9a of the door trim 9 is fitted into the fitting concave portion 6a, and the mounting base 4 is sandwiched between the extended end 9a and the door panel inner 1. Therefore weatherstrip 2 2 embedded metal core 10 to the mounting base portion 4, the attachment is firmly carried out compared with the case where no embedded metal core 10. In the door trim 9, a clip 12 is fixed at a position slightly away from the weather strip 22 between the door panel 9 and the inner side of the door panel 9 so as to reinforce the force holding the mounting base 4.

The weather strip 22 shown in FIG. 10,
But is the same as the weather strip 22 shown in FIG. 9 differs only attaching position of the clip 12. That is, the clip 12 is directly attached to the door panel inner 1 via the stopper 13 or 14 on the attachment base 4, and the attachment of the weather strip 22 is further strengthened. Each of the weather strips 21 and 22 is attached to a hinge portion of the door, and when the door is opened and closed in the opening and closing direction, the weather strip is compressed in a substantially vertical direction with respect to the extended surface of the door trim 9 so that the weather strip does not easily fall off. .

[0016] Figure 11 shows the mounting structure of the section C-C section of the weather strip 21 of the door body Da portion shown in FIG. 1, is similar to the case of the weather strip 21 of Figure 8, attached The base 4 is not clamped by the extended end 9a of the door trim 9 but by the garnish 8.

FIG. 12 shows the mounting structure of the weather strip 22 in the section taken along the line DD in FIG. 1. The weather strip 22 is formed in a U-shaped cross section in which the mounting base 4 embeds the core 10. Door trim 9 in the fitting recess 6a.
The extension end portion 9a is fitted in and the attachment is performed more firmly. Since the weather strip 22 is provided with the projection 1a on the door panel inner 1 as in the case of FIG. 7 , it is possible to prevent the weather strip 22 from falling off when the door is opened and closed in the opening and closing direction a.

[0018] As described above, the mounting structure of the weather strip of the present invention, the door frame F portion and the door body Da portion of the peripheral portion of the motor vehicle door D shown in FIG. 1,
Although different modes are shown, for example, FIG. 7 and FIG.
9 and FIG. 7 and FIG. 12 are possible, and a wider variety of combinations are possible.

[0019]

According to the present invention, when the weather strip is mounted on the door of the automobile, the fitting recess which is deeply recessed along the mounting surface of the mounting base of the weather strip,
The weather strip can be mounted extremely simply by fitting the extended end of the garnish or door trim and holding the mounting base between the extended end and the door panel inner. That is, like the conventional weather strip mounting, a retainer or a strong mounting tape is interposed between the mounting base and the door panel inner at the garnish mounting location, or the mounting base and the door panel inner at the door trim mounting location. Are connected by fasteners, and there is no need to perform complicated terminal processing of the door trim or affixing a cloth tape or the like for soundproofing, etc., so that the cost can be reduced accordingly.
